i am facing some issue here
1. it ask for next disk specially for data.srep (see the pic please) . it may be due to some error in my installer.ini (please take a look for that).

It extract everything smoothly after that.

2. it goes slowly upto 4% (extraction and installation) and then direcly jump from 4% to 17%.
after that there is no problem in installation percentage.

is it okay?
